TL;DR: In this paper, the authors examined the environmental competence of Bio-Synthetic Paraffinic Kerosene (Bio-SPKs) against conventional Jet-A, through development of a life cycle GHG model (ALCEmB) from a "cradle-grave" perspective.

TL;DR: In this article, the authors examine and analytically review the thermal management systems proposed over the past six decades for gas turbine civil aero engines and identify the remaining research questions that need to be addressed to enable this important technology to be adopted by next generation of aero engine with complicated designs.

TL;DR: The potential solutions for the remaining research challenges for application to aerospace engineering problems in the future include the implementation of enhanced and modified optimization algorithms and hybrid optimization algorithms in order to achieve optimal results for the advanced engine modelling and controller design procedure with affordable computational effort.

TL;DR: In this paper, the authors investigated the technical performance of turboshaft engine cycles based on existing simple cycle and its projected modified cycles for civil helicopter application and found that the modified engine cycles with unconventional components exhibit better performance in terms of thermal efficiency and specific fuel consumption than the traditional simple cycle engine.

TL;DR: In recent years, the increase in marine fuel prices coupled with stricter regulations on pollutant emissions set by the International Maritime Organization have promoted the research in new propuls... as mentioned in this paper.
